Specification of Letters Patent.

Application filed December 5, 1910.

Patented Sept. 15, 1914. Serial No. 595,592. 3

To all whom it may concern:

Be it known that I, CHARLES H. ATKINS, a citizen of the United States of America,

residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Vacuum-Producers, of which the following is a specification.

y present invention relates to improvements in vacuum producers of the kind or type in which a fluid, as water, that is under ressure, is allowed to escape into a device or producinga rarefaction or lowering of the atmospheric pressure therein. This device is designed to be connected with the floorimplement on the one hand and with a suitable discharge device for the waste fluid, as the sewer, on the other.

An important object of the invention is to provide means. for overcoming any back pressure that may be exerted at the waste connection. p r

A further object is to provide means toallow the commingled foreign substances and the waste fluid to flow uninterruptedly into the waste pipe and at the same time to.

provide means to overcome any back atmospheric pressure at the waste connection.

Broadly, the invention consists of one or more tubular members that are in direct communication with the floor implement, waste pipe,

and the escaping fluid from the source of supply, suitable meansbeing also avoid any back pressure to the flow of the fluid to the. waste pipe.

In the drawings forming part of this application,-Figure1 is a v ew showing the complete system asinstalled in a building,

sewer; also the pipe connection leading to the water supply. Fig. 2 is an enlarged vertical sectional View of the vacuum or eXhauster device, the section being taken on the line 2-2 of Fig. 3, looking in the direction of the arrow and showing the tubular members, the nozzles with their openings arranged in the axis of the tubular members, the head member in which the nozzles are located and to which the tubular members are secured, the pipe connections for source of fluid supply, and the stand-pipe, and the foot memher to which the lower ends of the tubular members are connected and the waste-pipe. Fig. 3 1s a transverse,

device being shown connected to the stand-pipe and the sectional view on the line 3-3 of Fig. 2, looking in the direction of the arrow. Referring to the drawings in detail, a indicates a suitable stand-pipe that is installed in the building, as shown in outline at Z), which is provided with suitable connections 0 for attaching a hose member, d, to which a floor implement e is attached. The vacuum producing, or air-exhauster device is designated as a whole by the letter f and comprises in detail a head member or piece 9 and a foot member or piece it. Located between the head and foot members are a plurality of tubular members i whichare received in bored out openings 9' and/ 0. A rod m is provided for connecting the members g and 72. together andfor holding the tubular members 2' in place. Thehead memher 9 is formed with a cored fluid chamber 0 with which the supply pipe p is connected for furnishing the operating iluid. A suitable shutoff 7'9 is placed in the pipe 79. Communicating with the cored-out portion 0 are nozzle elements 9 having conical-shaped openings 1' thcrethrough; the larger end of the opening being arranged toward the tubular members 2' ably in the aXis of the same, as clearly shown in Fig. 3. The discharge end of these nozzle elements is spaced from the ends of the tubular members i, as shown in Fig. 2 at s. This space constitutes a suction chamber and leads to, or communicates with, the standpipe or to which the floor implement a is connected.

p The manner in which the water or other fluid under pressure escapes from the conical-shaped openings 7' in the nozzle element q isshown by the broken lines 6 in Fig. 2. The foot-member or piece It to which the lower ends of the tubular members 2' are connected is formed with a contracted outlet or throat port 71 that is connected to a wasteor sewer-pipe u, as shown at e. The wastepipe at is providedwith the usual trap construction 'w. a I

In order to overcome and prevent any atmospheric back-pressure, an outlet to the atmosphere is shown at 0, which outlet opening is in open communication with the waste-pipe a; and, as shown, is connected back of the trap to. This outlet pipe 00, as will readily be understood, serves the purpose of permitting the air which. has been drawn into the stand-pipe a to escape to the and preferexperiments members 11,

has been drawn into the stand-pipe will, as

stated, escape through the outlet pipe 00.

The operation may be briefly stated as follows: When fluid, under pressure, is permitted to enter the cored-out portion 0 of the head member y it escapes from the conical-shaped openings 7' in the manner shown at i and passes into and through the tubular members i. -'Whenthis fluid flies across the spaces a rarefaction of the air in this space occurs and consequently in the stand-pipe a, pipe d, and at the floor implement e, whereby light particles, as dust, lint, etc., are car.-

1 can be operated at a small expense.

ried,as shown at '3, across the space 8 and through the tubular members i to the waste- 5 I ipe u. i tion herein described involves'an enlarged It should be stated, that observation and show the longer the tubular the greater will be the suction effect, orin other words, a higher degree of r'arefaction or vacuum effect is produced at 'thefioor implement 6.

he atmosphere by means of the pipe w, and the carrying away of the foreign substance and water in the waste-pipe u have alreadyv been described. "The contracted portion b which causes the contents of the tubular: v to come together, assists in drawing the air, water, and foreign substances.

members i downward through the members i and into the waste-pipe u.

I have found by experiment that the posi* tion of the vacuum producing device fis equally as eflicient when placed in other positions than the vertical one. It operates;

practically as efficiently when placed in substantially a horizontal position, the reason.

being that the rapid flow of water through the tubular member 2' is practically independentof the force of gravity, as can readthe number of feet a fluid will flow in a second under, say, a pressure of 100 lbs, to the square inch, and

ilybe seen by comparing the accelerative effect of gravity in the same time, this feature of being able to use the exhauster in :almost any position between the horizontal and vertical being an impor- 'tant onesince it enables this part of the.

vacuum cleaner to be more readily installed inplaces where there would be no room in a vert1cal-one. The'exhauster part of mysystern is, therefore, not limited to a vertical position.

:A further important :feature'of system I is that it is practlcally independent of the The manner of es- 1 cape of the a1r drawn into the stand-pipe to water pressure. That isto say, it can be install-ed and successfully used in places where the pressure varies. If the fluid pressure is high then the system will successfully operate with three tubular members. If the water pressure is low more than three tubular members are required, as six or seven; The.

number of course varies with the water pres.-

sure, the object being to obtain the same suction effect at the implement .e, or in .other words to move the same volume of air.

The system is also applicable for the purposcs of ventilation and cooling dwellings. The air that escapes from the pipe as is not only free from any dust but has become cooled by being in contact with the water in the'tubular members i, and when itescapes from the pipe :0 will purify and cool the surrounding atmosphere. It will therefore be seen that I have devised a vacuum cleaner system and .an air exhauster' device for? use therewith that is very efficient and onethat ,It will also be observed that the construcsuction chamber having a large; and capacious inlet in open communication with the standpipe, in combination with an outlet 1 having an openvent, all of whichprovides means for carrying a large volume of air, and producing a moderate vacuum, these bemg necessary essent als ln a vacuumeleanin system.
